CVE-2026-53670

PREVAIL , a polynomial-runtime eBPF verifier using an abstract interpretation layer, is vulnerable to a verifier bypass prior to version 0.2.4 . In the EbpfTransformer::add() function, offset-variable updates are silently skipped when the destination register carries a non-singleton typeset (two ...

CVE-2026-53671

PREVAIL is a polynomial-runtime eBPF verifier. Prior to version 0.2.4 , its abstract transformer in do_mem_store (src/crab/ebpf_transformer.cpp) silently ignores writes through a T_CTX -typed base register, and the checker's T_CTX bounds arm never tests AccessType::write. An attacker can craft an...

librest: weak random number generation in PKCE implementation

A flaw was found in librest. The PKCE implementation for OAuth authorization uses the GRand function from the GLib API, a cryptographically insecure pseudo-random number generator. Because the generated "code verifier" lacks sufficient cryptographic entropy, a malicious actor can reverse-engineer...
